ABSTRACT:
Metal-containing or metalfree, monosubstituted or disubstituted phthalocyanines I which have one or two of the following radicals R as substituents on their benzene rings: R=bromine, cyano, C.sub.1 -C.sub.3 -alkyl, n-butyl, i-butyl, C.sub.5 -C.sub.20 -alkyl, C.sub.5 -C.sub.10 -cycloalkyl, fluorinated C.sub.1 -C.sub.6 -alkyl, C.sub.6 -C.sub.20 -aryl, XR.sup.1, where X is oxygen, sulfur, selenium, tellurium or imino (NH) and R.sup.1 is C.sub.1 -C.sub.6 -alkyl, fluorinated C.sub.1 -C.sub.6 -alkyl or C.sub.6 -C.sub.20 -aryl, or Si(R.sup.2).sub.3, where R.sup.2 is C.sub.1 -C.sub.6 -alkyl, each and every substituted benzene ring being substituted by only one R radical, are useful in Laser-optical recording materials.
